SYPHILID 



Syphilid, Syphilide (sif'-il-id) [ME., syphilis, syph- 

 ilis]. Any disease of the skin due to syphilis. S., 

 Acneiform, one of the early and rare forms of the 

 cutaneous manifestations of syphilis. Its favorite posi- 

 tions are the face and shoulders. It is marked by the 

 formation of flat pustules, about the eighth of an inch 

 in diameter, on a dark-red, raised base, with a narrow 

 areola. S., Annular. See Syphiloderma circinatum. 

 S., Bullous, a syphilitic skin-ulceration that occurs 

 in two forms, the rupial and li pemphigoid." They 

 differ from the other vesicular and pustular syphilids 

 in not being placed on a raised, red base, and the 

 areola is often pink, and not the usual raw-ham color. 

 S., Circinate. See Syphiloderma circinatum. S., 

 Ecthymatous, a form occurring only in the cachectic, 

 and characterized by r the presence of large pustules, 

 which may be superficial or deep, the former occur- 

 ring mainly in the early stage, the deep in the third 

 period. The lesion commences around a hair- follicle, 

 is about a third or a quarter of an inch in diameter, 

 dries into a greenish scab on a raised, red base, 

 develops slowly, and lasts for a few weeks. It is most 

 common on the lower limbs. S., Erythematous. 

 See Roseola, Syphilitic. S., Follicular, Miliary 

 Syphilid ; Syphilitic Lichen ; a variety of papular 

 syphilid in which the hair-follicles are the seat of the 

 lesion. The lesion may be large or small. The 

 larger occurs in the first six months of the disease, in 

 irregular groups of from three or four to twenty, on 

 the extensor aspect of the limbs and the back. The 

 papules are about the size of a large pin"s head or 

 millet-seed, bright-red at first, soon changing to 

 brownish-red, and crowned with a small scale. They 

 appear in crops. The small form is very rare, is most 

 common in women, and occurs in the first or second 

 year of the disease. The papules are the size of a 

 large or small pin's head, pink at first, then fawn- 

 colored, thickly crowded together in groups. S., Her- 

 petiform. See S. , Vesicular. S., Impetiginous, 

 Syphilitic Impetigo; small pustules, single or aggre- 

 gated, appearing on the scalp, and covered by yellowish- 

 gray or brown crusts, forming patches around a single 

 hair-group. S., Lenticular, one of the common, early 

 eruptions, often following closely upon or mixed up 

 with the erythematous lesion. The papules are few 

 or many, but not closely packed, and only grouped 

 around the mouth and genitals. The usual sites are 

 the forehead, lower part of the face, the nape and 

 back, the flexor aspect of the limbs, and about the 

 genito-anal passages. The lesions are from an eighth 

 to half an inch in diameter, distinctly raised, sharply- 

 defined, flatly convex, of a deep-red tint (though 

 they may be pale), firm and smooth. S., Macular. 

 See Roseola, Syphilitic. S., Miliary. See S., Follic- 

 ular. S., Nodular, Tubercular Syphilid ; convex 

 projections of the skin, too large to be called papules. 

 They are most common in the tertiary period, but 

 may also be an early manifestation. They vary 

 from a quarter to a half an inch in diameter, are 

 sharply defined, considerably raised, of the character- 

 istic coppery color, occasionally breaking down and 

 ulcerating, with thick scabs, and much inflammation 

 around, accompanied with much pain, and followed by 

 white, depressed scars. They are solitary or few on 

 the face, limbs, and trunk, but are not grouped, save 

 in the tertiary stage. S., Nummular. See Syphilo- 

 derma papulo-sguamosum. S., Orbicular. See 

 Syphiloderma circinatum. S., Papular, a papular, 

 syphilitic eruption on the skin or mucous mem- 

 brane. S., Pemphigoid, Syphilitic Pemphigus ; a 

 rare eruption in acquired syphilis and occurring almost 

 exclusively in the congenital form. It is usually
